Question

find the angle which is four times its supplement​

Answer 1

Answer:

144

Step-by-step explanation:

let the angle be x

supplementary angle = 180-x

(180-x)4 = x

720-4x = x

5x = 720

x = 144

Answer 2

hey there!✋

Two angles are said to be supplement if there sum add upto 180°

i.e,

A + B = 180°

according to Question, "A" be the angle which is four times it's supplement i.e,

A = 4(180-A)

5A = 720

A = 144°

so the angle which is four times it's supplement is

144°
